Lighting apparatus for automatic counting devices bacterial colonies.

摘要

Lighting apparatus for automatic counting apparatus of bacterial colonies. Comprises a support (2) accommodating opaque and dark means (3) capping of the base plate (4) lighting up the latter by light rays deflected by reflection means (5) from a light source (1). It has a video camera (6) Image pickup for counting conventionally. It is characterized by comprising means for varying the relative position between the reflecting means (5) and the plate (4), so that the lighting is adapted to the different types of media used for culture of bacteria. The reflector means is determined by an annular body (5) whose reflection surface is inclined so that the reflected light has a very low vertical component.
